"Pump brakes to build pressure...."

We attended a family reunion this weekend, and it was about a 5 hour trip one way. The random spring snowstorm made things a little dicey, but we made it ok.

However, half way through the trip something happened that I've never experienced before.

We had just pulled out to pass someone and as we moved through the slush in the middle of the road a rock got into one of the rear brakes and started squealing. This has happened before, usually just have to pull over and pop it into reverse to clear the rock.

However, a few seconds after the squealing started, a loud male voice came over the speakers and started giving instructions on how to deal with brake failure.

"Pump the brakes several times to build up pressure. Engage the emergency brake. Switch to manual mode and begin downshifting to allow the engine brake to slow the vehicle." The wording may have been slightly different. There was a lot going on at that particular moment so my recollection could be off a bit.

No warning lights on the dash, or any other indication of a problem. The rock worked its way out after about 30 seconds, and the brakes were fine the entire time.

Has anyone heard of this happening before?

Honestly, if there hadn't been 4 other people in the vehicle I might have though I'd imagined it. The only thing I can think of is that my wife had her phone plugged into the vehicle for Android Auto, and that the always listening Google heard me say something about a problem with the brakes and intervened with instructions.

Ok, it must have been the phone. I started searching for Google brake failure audible message and the AI overview had a section that was pretty well word for word what played during the event. Apparently the Pixel phones have a 'car crash detection' feature that might have triggered.
